Organisers of the International Champions Cup are expected to confirm United's involvement and the names of the other clubs involved, but the tournament will be on a smaller scale.

It means United's tour will last around two weeks rather than three - United manager Louis van Gaal has made it clear he does not favour a lengthy pre-season trip.

The time available is also an issue - this season does not finish until June 14 for United's England players, who will travel to Slovenia for a Euro 2016 qualifier on that date.

The congestion is increased by the 2015-16 Premier League season starting on Saturday August 8, a week earlier than usual and cutting the time available for pre-season activities.

Last summer United played Los Angeles Galaxy and then the International Champions Cup facing Real Madrid - in front of a crowd of more than 109,000 - plus Inter Milan and Roma before beating Liverpool in the final.

Real Madrid will not be involved this time - the Spanish current Champions League holders will be taking part in a sister tournament in Australia along with Manchester City.
